Safe Water Campaigner challenges Daily Telegraph Article

Sir,
The Drinking Water Inspectorate may be a watchdog, but it's a poor kind of dog which retreats to its kennel when challenged. In the course of my 40 plus years of campaigning, alone and with others, against the deliberate contamination of our water supplies with silicofluoride, (a corrosive, poisonous waste product) simply on the grounds of reducing children's tooth decay, I wrote to the DWI to express my concern and query its position on fluoridation. In its reply to my letter, in which I had drawn attention to the alleged 'safe' concentration of 1.0 part fluoride per million of water becoming massively increased by the simple act of heating the water, such as to make tea and boil vegetables, the DWI stated that it supplied a product conforming strictly to regulations. What the consumer did with it was beyond its control. The implications of that priceless piece of evasive officialdom should be considered carefully by domestic consumers, not forgetting food and drink manufacturers and industries raising steam. Would 'criminal negligence' be a suitable charge to bring against the DWI, or would we find it 'kennelled' beyond reach of of the judicial system?
